Moderately healthy humans function fine up to about

so as you go up from there. This is why aviation rules allow pilots
to fly unpressurized planes without restriction up to 10,000 feet, but
require supplemental oxygen if they stay above 10k for more than 30
minutes (or above 14k for any time).
Needless to say, mountain dwellers are more tolerant than that.
I spent a month at 12,000 feet in Cuzco, Peru. It took a couple days to
get acclimated (chewing coca leaves would've reduced this time). After
the initial queasiness passed, it was just a matter of conditioning to get
used to having less oxygen. When I got back home I felt great :)
